AND A VERY SPECIAL ONE AT THAT. TAKE A LOOK. THIS IS GREG ALTRINGER. THAT'S HIS GIRLFRIEND, ERICA. THREE YEARS. HE'S GOING TO PROPOSE AT THE CUBS GAME, AT WRIGLEY. HE'S GETTING NERVOUS. HE'S OKAY. THEY'RE GOING TO THROW UP. THEY'RE GOING TO THROW UP ON THE BIG JUMBOTRON. THEY'RE GOING TO THROW UP -- I'M GOING TO THROW UP. ERICA, WILL YOU MARRY ME? THE PROBLEM IS, ERICA NEEDS TO BE THERE TO SEE IT HAPPEN. OH, NO. THEY'RE GOING TO JOIN US LIVE HERE TO DISCUSS IT ALL. AS YOU CAN SEE, IT DID END WELL. ERICA AND GREG, JOINING US VIA SKYPE. SO, HOW DID THIS POSSIBLY GO WRONG? ERICA, WHERE DID YOU GO? WELL, I -- GREG HAD SENT ME TO GET A COUPLE BEVERAGES. APPARENTLY, HIS PLAN WAS TO LET EVERYONE AROUND US KNOW WHAT WAS GOING ON WHILE I WAS AWAY. AND HE WAS GIVING THE PEOPLE UP BEHIND HIM HIS CAMERA AND SOMEONE TO VIDEOTAPE IT AND TAKE PICTURES. GREG, WHEN SHE'S GONE, SHE'S GONE FOR A WHILE. WHAT ARE YOU THINKING AS THE SECONDS ARE TICKING AWAY? OH, I WAS SO NERVOUS. THE INNING WAS QUITE SHORT. AND WHEN TWO OUTS CAME, I TOOK OFF OUT OF MY SEAT, JUST TO FIND HER TO PULL HER OUT OF LINE. I NEEDED A QUICK SECOND TO GIVE MY CAMERA AWAY AND LET EVERYONE KNOW WHAT I WAS DOING. BUT THE LINES WERE LONG. AND THE INNING WAS SHORT. SO, IT JUST DIDN'T WORK OUT LIKE I WANTED IT TO. WE HAVE A FEW SECONDS. BUT QUICKLY, WE DID SEE IT HAPPENED THE OLD-FASHIONED. AND ERICA, YOU SAID YES. CAN WE SEE THE RING? I DID. YAY. WE REALLY DO APPRECIATE YOU JOINING US. AND CONGRATULATIONS. THANK YOU. CONGRATULATIONS, GUYS. CONGRATULATIONS.
